This collection showcases Edmonton’s rich telecom history from wooden three box wall telephones to rotary phones and beyond, and also houses functional switching equipment as well as an extensive library on telecommunications history.
The Collections were born out of an initial decision to save telephone equipment and directories that might otherwise have been thrown away, documenting generations of telecom workers who installed poles, laid cables, designed and managed technology which connects us all.
History of the Telephone
The telephone has long since overcome its early reception as an inferior form of telecommunication, becoming one of our most useful inventions. It has dramatically increased communication facilities, replacing many other forms of transmission as the preferred form.
1876: Alexander Graham Bell successfully transmits voicelike sound over an electric wire, marking the dawn of modern telecommunications history.
As early as the early 20th century, a physical style of telephone that would last was introduced. This included a carbon granule transmitter and electromagnetic receiver combined into one molded plastic handle; its coupling transformer, battery, and ringer housed in its cradle base unit. This phone was an innovation in telecommunications technology that made long-distance calling possible; its replacement came about through touch tone signaling allowing people to dial numbers faster without manually counting clicks on rotary dials – leading way towards mobile phones and their mobile internet.
Technology of the Telephone
The museum’s collection of telephone artifacts highlights the technological advancements made over the past 140 years in telecommunications. Complete with functioning equipment that shows their historical importance, this display depicts what an impactful collection it is.
Johann Philipp Reis developed the first electrical voice-transmission system in 1863 using a vibrating membrane that opened or closed an electric circuit – this innovation predated Alexander Graham Bell’s telephone invention that was patented in 1876.
Bell experimented with tuned reeds to transmit and receive not only exact pitches but more complex sounds that could be recognized as voice. He developed multiplexing to allow multiple voices to be transmitted simultaneously. Unfortunately, however, telephone technology at that point wasn’t sophisticated enough for practical communication devices; sound transmission required too much power over short distances to support it effectively; Bell’s telephony had to wait until more advanced technologies could support its expansion.
Telephone Artifacts
The museum boasts an incredible collection of telephone artifacts, from wooden wall phones and candlestick phones, classic rotary dials, operator switchboards and novelty telephones to working switching equipment and cases containing telephone wire insulators.
The collection not only fascinates those interested in telecom, but it is also a fun trip down memory lane for many visitors. They remember party line phones in kitchens, Scobie’s store phones in suburban homes, and that thrill of receiving an unexpected call from an old flame.
Our collection also houses historic Rockville Centre telephone directories, offering us a window into how communication has changed over time and its impact on the community.
Interactive Stations
The Telephone Historical Centre Collections is a museum featuring telecom artifacts ranging from old wall phones and manual switchboards, through automated switching networks and automated switching networks, to automated switching networks themselves. Furthermore, there is also an on-site library offering vintage telephone publications for research.
As opposed to many museums, this one does more than simply display technology’s evolution; rather, it invites its visitors to become actively involved with it by featuring interactive stations where people can experiment operating early telephones and switches.
Modern phone calling may seem magical, but its origins weren’t always this easy. This museum provides a window into past where cords and wires were everywhere – including operator switchboards, test equipment for aerial wire and lineman tools for pole erection.
The Telecom Historical Centre in Gridley, Illinois is a truly amazing independent telecom museum which can be visited free with volunteer support. Their collection of antique telecom equipment spans from operator switchboards and linemen’s tools to replicas of Alexander Graham Bell’s original phone!
